When trouble arises
WARNING
■When using the compact
spare tire
●Remember that the compact
spare tire provided is specifi-
cally designed for use with your
vehicle. Do not use your com-
pact spare tire on another vehi-
cle.
●Do not use more than one com-
pact spare tires simultaneously.
●Replace the compact spare tire
with a standard tire as soon as
possible.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
■When the compact spare tire
is attached
The vehicle speed may not be
correctly detecte d, and the follow-
ing systems may not operate cor-
rectly:
• ABS & Brake assist
• VSC
• TRAC
• Automatic High Beam (if
equipped)
• Dynamic radar cruise control with full-speed range (if
equipped)
• Dynamic radar cruise control (if equipped)
• EPS
• PCS (Pre-Collision System)
• LDA (Lane Departure Alert with steering control) (if equipped)
• LTA (Lane Tracing Assist) (if equipped)
• Tire pressure warning system
• Navigation system
■Speed limit when using the
compact spare tire
Do not drive at speeds in excess
of 50 mph (80 km /h) when a com-
pact spare tire is installed on the
vehicle.
The compact spare tire is not
designed for driving at high
speeds. Failure to observe this
precaution may lead to an acci-
dent causing death or serious
injury.
■After using the tools and jack
Before driving, ma ke sure all the
tools and jack are securely in
place in their storage location to
reduce the possibility of personal
injury during a collision or sudden
braking.
NOTICE
■Be careful when driving over
bumps with the compact
spare tire installed on the
vehicle.
The vehicle becomes lower when
driving with the compact spare tire
compared to when driving with
standard tires. Be careful when
driving over uneven road sur-
faces.

COROLLA H/B_U
recharge the battery of your
vehicle.
5 Open and close any of the
doors of your vehicle with the
engine switch OFF.
6 Maintain the engine speed of
the second vehicle and start
the engine of your vehicle by
turning the engine switch to
ON.
7 Once the vehicle’s engine
has started, remove the
jumper cables in the exact
reverse order from which
they were connected.
Once the engine starts, have the
vehicle inspected at your Toyota
dealer as soon as possible.
■Starting the engine when the
battery is discharged
The engine cannot be started by
push-starting.
■To prevent battery discharge
●Turn off the headlights and the
audio system while the engine is
off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the battery is removed or
discharged
●Information stor ed in the ECU is
cleared. When the battery is
depleted, have the vehicle
inspected at you r Toyota dealer.
●Some systems may require initial-
ization. ( P.539)
■When removing the battery ter-
minals
When the battery terminals are
removed, the information stored in
the ECU is cleared. Before remov-
ing the battery term inals, contact
your Toyota dealer.
■Charging the battery
The electricity stored in the battery
will discharge grad ually even when
the vehicle is not in use, due to nat-
ural discharge and the draining
effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the battery may discharge,
and the engine may be unable to
start. (The battery recharges auto-
matically during driving.)
■When recharging or replacing
the battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the bat-
tery is discharged. Use the wire-
less remote control or the
mechanical key to lock or unlock
the doors.
●The engine may not start on the
first attempt after the battery has
recharged but will start normally
after the second attempt. This is
not a malfunction.
●The engine switch mode is memo-
rized by the vehicle. When the
battery is reconnected, the system
will return to the mode it was in
before the bat tery was dis-
charged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the
engine switch wa s in before the
battery discharged, be especially
careful when reconnecting the
battery.
■When replacing the battery
●Use a battery that conforms to
European regulations.
●Use a battery that the case size is
same as the previous one (LN2),
20 hour rate capacity (20HR) is

5058-2. Steps to take in an emergency
COROLLA H/B_U

When trouble arises
equivalent (60Ah) or greater, and
performance rating (CCA) is
equivalent (360A) or greater.
• If the sizes differ, the battery can- not be properly secured.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle is not used is a short time,
the battery may discharge and the
engine may not be able to start.
●For details, consu lt your Toyota
dealer.
WARNING
■When removing the battery
terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, l eading to a fire
in addition to electrical shocks
and death or serious injury.
■Avoiding battery fires or
explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal to come into
contact with any other parts or
metal surfaces in the area, such
as brackets or unpainted metal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighters or allow open
flame near the battery.
■Battery precautions
The battery contains poisonous
and corrosive acidic electrolyte,
while related parts contain lead
and lead compounds. Observe
the following precautions when
handling the battery:
●When working with the battery,
always wear safety glasses and
take care not to allow any bat-
tery fluids (acid) to come into
contact with skin, clothing or the
vehicle body.
●Do not lean over the battery.
●In the event that battery fluid
comes into contact with the skin
or eyes, immediately wash the
affected area with water and
seek medical attention. Place a
wet sponge or cloth over the
affected area until medical
attention can be received.
●Always wash your hands after
handling the battery support,
terminals, and other bat-
tery-related parts.
●Do not allow children near the
battery.
NOTICE
■When handling jumper cables
When connecting the jumper
cables, ensure that they do not
become entangled in the cooling
fan or engine drive belt.

Votre véhicule est équipé de COUSSINS GONFLABLES INTELLI-
GENTS conçus selon les normes de sécurité américaines applica-
bles aux véhicules à moteur (FMVSS208). L'ensemble de capteurs
de coussins gonflables (ECU) régule le déploiement des coussins
gonflables sur la base des informa tions qu'il reçoit des capteurs,
etc., indiqués ci-dessus dans le schéma illustrant les composants du
système. Parmi ces informations figurent la gravité du choc et l'occu-
pation du véhicule par les passagers. Le déploiement rapide des
coussins gonflables est obtenu au moyen d'une réaction chimique
dans les dispositifs pyrotechniques, qui produit un gaz inoffen sif per-
mettant d'amortir le mouvement des occupants.
WARNING
■Précautions relatives aux
coussins gonflables SRS
Respectez les précautions suiva-
ntes concernant les coussins gon-
flables SRS.
Le non-respect de ces précau-
tions peut occasionner des bless-
ures graves, voire mortelles.
●Le conducteur et tous les pas-
sagers du véhicule doivent por-
ter correctement leur ceinture
de sécurité.
Les coussins gonflables SRS
sont des disposit ifs supplémen-
taires à utiliser avec les cein-
tures de sécurité.
●Le coussin gonflable conduc-
teur SRS se déploie avec une
force considérable, pouvant
occasionner des blessures
graves, voire mortelles, si le
conducteur se trouve très près
du coussin gonflable. L'autorité
fédérale chargée de la sécurité
routière aux États-Unis
(NHTSA) conseille:
La zone à risque du coussin gon-
flable conducteur se situant dans
les premiers 2 à 3 in. (50 à 75
mm) de déploiement, vous placer
à 10 in. (250 mm) de votre cous-
sin gonflable conducteur vous
garantit une marge de sécurité
suffisante. Cette distance est à
mesurer entre le centre du volant
et le sternum. Si vous êtes assis à
moins de 10 in. (250 mm), vous
pouvez changer votre position de
conduite de plusieurs façons:
• Reculez votre siège le plus pos- sible, de manière à pouvoir
encore atteindre confortable-
ment les pédales.

plus sûrs pour les nourrissons
et les enfants que le siège du
passager avant.
●Ne vous asseyez pas sur le
bord du siège et ne vous
appuyez pas contre la planche
de bord.
●Ne laissez pas un enfant rester
debout devant le coussin gon-
flable passager avant SRS ou
s'asseoir sur les genoux du pas-
sager avant.
●Ne laissez pas les occupants
des sièges avant voyager avec
un objet sur les genoux.
●Ne vous appuyez pas contre la
porte, le rail latéral de toit ou les
montants avant, latéraux et
arrière.
●Ne laissez personne s'age-
nouiller sur le siège passager
en appui contre la porte ou sor-
tir la tête ou les mains à
l'extérieur du véhicule.
●Ne fixez rien et ne posez rien
sur des emplacements tels que
la planche de bord, la garniture
du volant et la partie inférieure
du tableau de bord.
Ces éléments peuvent se trans-
former en projectiles lorsque les
coussins gonflables conducteur,
passager avant et genoux SRS
se déploient.
